Abstract
Abstract An air humidifier is provided with an enclosed evaporator wherein electrodes extend into water within the evaporator and electrical conduction between the electrodes occurs through the water. The heat so generated converts the water to steam and the evaporator has a steam chamber connected, by a nozzle equipped steam line, to the air which is to be humidified. The water sump of the evaporator is connected to a water supply by means of a feed line through which a constant quantity of water is supplied in an amount exceeding the amount of water evaporated. The sump is also connected to an overflow discharge line. A discharge orifice, communicating with the feed line and the overflow discharge line, is arranged in the bottom of the evaporator and the overflow is vertically adjustable to control the water level in the evaporator.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
331 words
A water evaporator comprising, in combination, an evaporator vessel, spaced electrodes each having a length exposed in the interior of said vessel, water supply means opening into said evaporator vessel in the lowermost portion of said evaporator vessel for admitting water into said vessel to immerse said electrodes so that the electrical circuit between said electrodes is made through water in said vessel, current in said water heating said water to convert said water to steam and said water supply means further operative to provide water in excess of the evaporation capability of said evaporator, means communicating with the interior of said vessel above the level of said water for conveying steam to air to be humidified, means defining a water overflow line communicating, through a water discharge from said evaporator vessel located in the lowermost portion of said evaporator vessel and through which excess water supplied to said evaporator vessel is discharged, with the interior of said vessel and having a vertically adjustable overflow point so that the level of water in said vessel, and accordingly the amount of electrode immersion in water, can be controlled by varying the vertical position of said overflow point, a distribution plate arranged above the level of the opening of said water supply means into said evaporator vessel extending between the walls of said evaporator vessel and having means defining a plurality of apertures therein so that said distributor plate distributes water uniformly over the cross section of said evaporator vessel, said water discharge comprising at least one opening above the level of said distribution plate in the lowermost area of said evaporator vessel and said water discharge opening communicating with said water overflow, a top on said evaporator vessel, and a holLow generally cylindrical wall extending from said top into said evaporator vessel and terminating at the level of said water discharge opening, said cylindrical wall spaced from said evaporator vessel and defining therewith a generally closed space open only at the bottom.
Claim 2
Dependent Claim
331 words
A water evaporator comprising, in combination, an evaporator vessel, spaced electrodes each having a length exposed in the interior of said vessel, water supply means opening into said evaporator vessel in the lowermost portion of said evaporator vessel for admitting water into said vessel to immerse said electrodes so that the electrical circuit between said electrodes is made through water in said vessel, current in said water heating said water to convert said water to steam and said water supply means further operative to provide water in excess of the evaporation capability of said evaporator, means communicating with the interior of said vessel above the level of said water for conveying steam to air to be humidified, means defining a water overflow line communicating, through a water discharge from said evaporator vessel located in the lowermost portion of said evaporator vessel and through which excess water supplied to said evaporator vessel is discharged, with the interior of said vessel and having a vertically adjustable overflow point so that the level of water in said vessel, and accordingly the amount of electrode immersion in water, can be controlled by varying the vertical position of said overflow point, a distribution plate arranged above the level of the opening of said water supply means into said evaporator vessel extending between the walls of said evaporator vessel and having means defining a plurality of apertures therein so that said distributor plate distributes water uniformly over the cross section of said evaporator vessel, said water discharge comprising at least one opening above the level of said distribution plate in the lowermost area of said evaporator vessel and said water discharge opening communicating with said water overflow, a top on said evaporator vessel, and a holLow generally cylindrical wall extending from said top into said evaporator vessel and terminating at the level of said water discharge opening, said cylindrical wall spaced from said evaporator vessel and defining therewith a generally closed space open only at the bottom.
Claim 3
Dependent Claim
83 words
The water evaporator of claim 1 including an outer wall surrounding said evaporator vessel and defining therewith an overflow space communicating with the interior of said evaporator vessel through said discharge opening and providing a part of said water overflow, and wherein said overflow includes a generally cylindrical member extending through the bottom of the space between said outer wall and evaporator vessel wall into said overflow space with the upper end of said cylindrical member providing the overflow point for said overflow.
Claim 4
Dependent Claim
46 words
The water evaporator of claim 2 including means defining a nozzle in said means for conveying steam from said evaporator vessel and operative to retard the flow of steam from said evaporator vessel and thereby produce a back pressure on the water in said evaporator vessel.
